Iomega has continued its push into entry-level network attached storage (NAS) devices, with the release of two new products with larger storage capacities and compatability with its new Rev removable hard drives.

The NAS 200d has been announced a month after the company first made available the 200m and 300m servers. However, the 200d works with both conventional ATA drives and the Rev removable hard drives that it began shipping earlier this year.

The cube-shaped appliance will start at $1,399 and gives small businesses a way of adding a file server to their networks without having to pay the client licensing fees associated with a Windows Server 2003 system, said Wayne Arvidson, a director with Iomega's professional storage solutions group. "You plug it into a network and it publishes itself as a drive to everyone on the network," he said.

The 200d will come in two models: a 320GB model with two 160GB Serial ATA drives, and a 480GB model with three drives. Because they will be Iomega's first NAS devices not designed to be mounted on server racks, the storage servers will be more appropriate for small and medium-sized business customers that do not have racks of servers, said Brad Nisbet, program manager with IDC.

The 320GB 200d server connects to the network using a 10/100/1000 Ethernet interface. The 480GB server includes two such ports. For adding additional storage or tape backup devices, the NAS appliances will have four USB 2.0 ports. The 480GB model will also have an UltraSCSI 320 port, Iomega said.

By September, Iomega plans to begin selling a Rev drive kit that can be inserted directly into the 200d chassis. This will give users another way of creating removable backups of their data, Arvidson said. The Rev drive kit is "probably going to be similarly priced" to Iomega's existing Rev drives, which cost $350, Arvidson said.

The 200d will offer users a Windows-based alternative to Linux-powered NAS devices such as those sold by Snap Appliance, Arvidson said. "Having a Microsoft-based solution makes it very easy for small and medium businesses," he said. "There is native support for Active Directory and the management screens are exactly like what you have with your Microsoft desktop," he said.

The NAS 200d with 320GB of storage will have a list price of $1,399. The 480GB model will be $1,999. Both products will begin shipping in the US, Canada and Latin America in June. The UK will have to wait until September.
